JOHN M. WILLIAMS, OF PITTSBURG, PENNSYLVANIA.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 257,118, dated April 25, 1882.

Application filed February 28, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN MORRIS WIL- LIAMS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented oer-- tain new and useful Improvements in Lubricators, of which the following is a full, clear, and exact description.

My invention relates to a lubricating device which is more particularly intended for application to a hanger provided with a bearing for a horizontal shaft; but it may also be employed for lubricating car-axle and other journals.

The invention consists in a novel construction, arrangement, and combination of an outer cup or vessel provided with a neck having an external and internal thread, with vertical grooves in the internal thread; an inner cup or vessel provided with an externally-threaded neck havingvertical grooves therein; a coiledwire spring resting in the inner vessel and having its lower end projecting through the neck thereof; a cap or cover inclosing both of said vessels, and certain details hereinafter more particularly described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a central vertical section of my invention in position for use. Fig. 2 is a top view of the same with the cap or cover removed. Fig. 3 is a bottom view of the outer vessel. Fig. 4 is a bottom view of the inner vessel.

A representsa portion of a journal or shaft, and B a portion of a journal box or hearing having my improvement applied thereto. The outer vessel or cup, 0, is goblet-shaped, with a hollow neck, 0. The exterior of the neck 0 is provided with a screw-thread, d, for engagement with a threaded hole in the box or bearing B, and the interior of the neck is provided with a thread, d for the purpose hereinafter described. In the internal thread, d are a number of vertical semi-cylindrical grooves, e. Theinner vessel or cup, F, is also gobletshaped, but considerably smaller than the outer vessel, and is provided with a hollow neck, f, somewhat longer than the neck of the outer vessel.

The neck f is provided with an external apparatus isthen ready for use.

thread, 9, for engagement with the internal thread, (1 in the neck of the outer vessel, and

in this external thread are vertical semi-cylindrical grooves 71, corresponding in number, shape, and depth with the grooves e in the neck f.

J represents a coiled-wire spring, the lower end of which is straightened out and extends down through the neck f, so as to touch the surface of the shaft orjournal A. The upper end of the spring is also straightened out for a short distance, and bears against the inner surface of a cap or cover, K, which fits over the top of both the vessels. Said cap K and the outer vessel, 0, are screw-threaded to facilitate the attachment and removal of the cap.

On the outer surface of the inner vessel, F, is a flange, L, in the edge of which a number of notches, l, are formed. A U shaped spring, M, has one end attached to the inner surface of the outer vessel, 0, and the other end bears against the edge of the flange L and engages with the notches l. i

The inner cup or vessel, F, is attached to the outer vessel, (J, by screwing the neck f into the neck 0. When the apparatus is to be placed in position for use the neck 0 is screwed into place in the box or hearing B, the inner vessel, F, having its neckf in such a position in the neck a that the vertical grooves e and h engage with each other and form tubes leading from the outer cup or vessel, 0, in which position it is held by the engagement of the spring M with one of the notches l. The outer cup is then supplied with oil, the spring J is placed in position in the cup F and said cup is supplied with tallow or other suitable grease, the cap or cover K is placed in position, and the As the shaft or journal revolves the oil from the cup 0 flows to it through the tubes or channels formed by the grooves e and h, and the heat generated in the coiled-wire spring J by the friction of the shaft or journal melts the tallow in the vessel F, so as to allow it to How to said shaft or journal.

By turning the cup F so as to disengage the grooves e and h from each other the-flow of oil maybe stopped and the grease used alone, and by removing the spring J the oil may be used alone.

and the cap or cover K, of the inner vessel, F,

having grooves on the exterior of its neck, and

the coiled-wire spring J, substantially as and for the purpose set forth.

3. The combination of the outer vessel, G, having grooves e in the interior of its neck 0,

and the inner vessel, F, having grooves h in the exterior of its neck f, substantially as and for the purpose herein described.

4.. The combination, with the outer vessel,

.0, having grooves on theinterior of its neck,

and provided with the spring M, of the inner vessel, F, having grooves on the exterior of its neck, and provided with the flange L, having notches l, substantially as and for the purpose set forth.
